Filed: 1973-12-07
Abstract: 1489873 Microwave line couplings MICROWAVE & ELECTRONIC SYSTEMS Ltd 7 March 1975 [7 Dec 1973] 56944/73 Heading H1W Planar transmission lines are coupled by ferrimagnetic film elements. Thus co-planar waveguides 14a, 14b, Fig. 2, are coupled to a slotline 15 by discs 12a, 12b of suitable ferrimagnetic material, e.g. yttrium iron garnet (YIG). The material is deposited epitaxially upon a suitable single-crystal substrate which may be the dielectric substrate of the lines 14a, 14b, 15, e.g. of gallium gadolinium garnet (GGG). In order that the RF fields of both kinds of line may couple to the discs 12, a bias field must be applied perpendicular to both. In this instance, the bias field H 0  is applied in the plane of the discs 12 and in the direction of propagation of the lines. The field H 0  determines the resonant frequencies of the discs 12. As shown in Fig. 4, two shortcircuited co-planar waveguides 54, 55 are coupled by a ferromagnetic film disc 52 to which a bias field H 0  is applied in a direction normal to the plane of the disc.

Filed: 1973-12-31
Abstract: 1425666 Facsimile scanners PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Dec 1973 [12 Jan 1973] 60308/73 Heading H4F A facsimile scanner employs an array of glass fibres each provided with an electrically con-   ducting coating the fibres acting as light conducting means when scanning an original to generate signals corresponding to a point-bypoint analysis (reading) and as electrical conducting means to produce point electro-static charges when scanning a recording medium to produce a copy corresponding to input electric pulses (writing). The fibres comprise a core 1 (Fig. 1), of transparent material surrounded by a sheath 2, also of transparent material, but having a refractive index which is less than that of the core, each fibre being provided with an electrically conducting coating 3. Fig. 2, shows the general scheme in which, for "reading", light reflected by an original 5 illuminated by a source 6 is conducted by fibres such as 4, to a photoelectric pick-up device 7 whereas, for "writing", a pulse generator 9 supplies pulses between the electrically conducting coating of the fibre and a counter electrode 8. The fibres are arranged in a linear array adjacent the "reading"/"writing" surface and the other ends are grouped in a circle 21 which is "scanned" by a rotating photo-diode 12 in the "reading" mode, whilst, in the "writing" mode, a rotating contact 13 distributes electric pulses to the conductive coatings. Fig. 4, shows an arrangement which allows a reduction of transmission time by grouping the fibres 40 in banks each having the same number of fibres, employing a number of photo-electric devices 41 equal to the number of fibres in a single bank, illuminating the area adjacent to each fibre in a bank by optical fibre groups 41 each receiving light from respective selectively operated light sources 42 and supplying the signals generated by all of the photo-electric devices 41 when a source 42 is operated to a shift register which is then read out sequentially after each light source 42 has been operated. When the arrangement of Fig 4 is employed for recording (writing) separate counter electrodes corresponding to the banks of fibres are employed.
